VIBRATOR HOOK.

Application filed September 12, 1921.', Serial No. 500,194.

To all whom 'it may concern: i v Be it known that we, JOHN T. STONEY andKLEMENS PURWIN, both citizens of the United States, and residents ofCleveland,`

county of Cuyahoga, and State of Ohio, have invented a new and `usefulVibrator Hook, of which the following is a specificaf a hook or similarmechanism with an elii-4 cient means for setting up vibrations in thesehooks or other similar mechanisms for the purpose of removing sand,dirt, etc. froml connection with source of fluid pressure objectsconnected to thesehooks etc.

In many instances it is necessary that` sand, or dirt, or y other matterbe removedy v from the inside or outside of boxes, flasks, etc., butsuch matter usually adheres to the walls of these boxes etc. andrequires con#v siderable effort and time for its removal. In

remove this sand 'by manual scraping and pounding on theiiask with amallet or other tool and, quite frequently, the flask is broken thereby.j n T u n n y The present invention aimsto remove the sand from theseflasks as well as other objects which are enculnbered yin a similarmanner, by setting up vibrations in the material of a hook or othermeans upon which the flasks etc. are suspended orsupported and therebyshake out allsand etc. without manual effortl and in niuch less timethan such operation could be 4done by manual means. o f

An apparatus to yattain the above object is shown in the accompanyingdrawing and described in` this specification, but it is unT derstoodthat various changes and modifications may be made within the spirit ofthis invention and without sacrificing any of the advantages containedkin the appended claims. f-

The accompanying drawing illustrates a vibrator hook -mechanism in asingle perspec tive view, partly` broken away to show the vibratormechanism clearly.

This hook mechanismy The bale A, made ofsuitabl'e material, has the arms10 and 11, and the cylindrical por comprises the bale l tion 12ysubstantially at right angles to these arms, and the loop 13 which isadapted to be engaged by a crane hook or other means.

Thisk portiony12 has the counterbore 14 which is open at the bottomwhere it is threaded as shown, but which is closed at the top by the.wall 15 integral with the portion 12 'of thevbalerA. This wall 15 hasthe opening 16 into which the anvil block 17 is driven. This rportion.12 further has the exhaust `ports 18 and `19, and the inlet chamber 20,

and theinletport 21 opening into the chamber20, and the boss 22 intowhich the supply pipe 23 is screwed. A rubber hose or other meansmay be.attached to the pipe 23 for Inside of this counterbore 14 is the sleeve24 which is renewable when worn and is provided: withy -the exhaustports 25 and 26 corresponding-to the exhaust ports 18 and 19 and withthe inlet,Y ports 27 and 28 properly spaced and opening into the chamber20.

This proper .spacing of the inlet ports 27 i and y28 will Iappearhereinafter.

"This, sleeve 24 may be renewed when worn ,so that the bale A itself isnot affected byv wear and this sleeve also establishes a wall betweenthe main bore of the cylinder and the chamber 2O so that the entering`fluid pressure cannot reach the inside of the sleeve 24 except throughthe inlet ports 27 and 28.

The plug'29 is screwed into the threaded :end of the bore 14 and has therounded outer end 30 and the anvil boss 31 projecting a short distanceoutside of the main body of the plug 29.

This anvil boss 31 and the anvil block 17 should be suitably hardened toprevent upsetting, but should not be so brittle that pieces may breakofll and interfere with the action of the vibrator. y

, Through the lower portion of the cylindrical portion 12 and properlyspaced 1n relation yto the round endl 30 of the plug 29 is therectangular opening 32 to receive the k,taper key r33.

Q9 and the material of the bale A. and such joint can be'take'n'up incase the elements wear and can be held tight by means ot' the nut 34which is not affected by the action of the vibratorV mechanism since itacts substantially" at 'right angles thereto and the taper of the keyneed not be suiiiciently great to exert any appreciable force againstthis nut.

It is not necessary that the plug Q9 be threadedinto theopeningl4 andany suit` able' 'means of vclosing` thejlower end et .this o'pening'niaybe employed.

'Ifti'sfimportant however', whatever mechanism @s employed, that therblock 17 and the plug' 29 bear directly upon the material ot theba'le Aso that 'the'vibrator mechanism acts directly against the material ofthe rbale A and creates vibrations' therein.'

' 'Inside'o't the sleeve24] is the plunger 35 which is provided with theanvil projections 3 6 and 37 and'with the grooves 38 4and 39, suitablyspaced as will appear hereinafter, and with the lholes 40 and l41openingiinto the grooves 38 rand V39 respectively.

` yllhe anvil 'projections 36e-nd 37, as well as the 'plunger'as 'a.'whole, are properly hardened to mitigate wear of the plunger propery as`'well fas upsetting' ot the projections 36 and 37, butithese projectionssheuld not be suitii'ciently brittle to'chip or permitv pieces to break'off and interfere with the 'action of Athe vibrator mechanism.

The hooks B shownhave the openings 43, preferably rounded at the top asshown, by which they 'are ysuspended on the ends of the bale 1 and areheld there in suitable position -by the pins 44, the rounding of thetops. or'v the openings 43 permits the hooks ,to rock on the arms l()and il ojlthe bale A.

The lower end of, thesehooks are adapted to engage" the projections v ofthe vflask 46r` shown in dot and dash lines. These lower' endsf'may bemodi-fiedto engage other. articles and the. upper ends maybemoditied'tor rigid 'or other connection to the bale.

` he operation of this apparatus is as follows:

Fluid pressure, such as compressedl air for -1nstance,isadmitted't-hrough the pipe 2 3 in to the chamber'QO. The. plunger is now.in its,lowest position7 as shown inthe drawing, dueto itsown weight4when the vihiatpr, mechanism ismat rest. Fluid'pres# 'sure' now' flows"from4- the" chamber l 20,` threugh ythe port 28, into ,the groove 39,through ,the hole. 41, and into the' space 47. At thesamef time, thespace48l is in communicationwith the open air through the hole 40, thegroove 38, andthe exhaust .perts nd- 18 The exhaust port-126 isbisserl-eager?- The iuid pressure in the space 47 now forces the plungerupward untily it strikes the block 1'? at which stage the groove 38registers with the inlet port Q7, admitting fluid pressure to the space4Sthrough the hole 40 and forcing,` the plunger downward until itstrikes the plug 29; during; this' stroke, the fluid pressure escapesfrom the space 47 through the hole 4l, the groove 39, and the ports 26and v19. This operation is repeated and continuesto repeat automatically as` long as fluid pressure' is supplied to the chamber 20.`

The relative 'spacing ot the lg'romjes 3S and and the ports 25. 26,' 27,and 2S should be so arranged that the plunger opens and closes theseportsv at the proper time. d i

,ldlhen the plunger operates as set forth and strikes the anvils sharpvibrations are set up or created in the anyils and are transmitteddirectly to the material Aof the bale A and from. there to the hooks, Band to the flask '46. These vibrations in the flask 46 cause all sand,etc., to'be loosened and removed'therefrom in much less 'time thanmanual effort could d'o so.

lt will. be seen that y'this apparatus is ecient since it removes sandetcQeitectively and'lquickly, hast'ew parts, the parts subject to wear`can be adjusted 'and re'- newed, and the vibrations created I4aretra-nsniitted directly to the article operated upon.
